Reimplemented from ge::Grid2D.

void ge::CartesianGrid2D::create	(	vmml::Vector2ui	_pointCounts,
		double	_stepsize
	)

Set up a cartesian grid with origin 0.0, 0.0.

Parameters

_pointCounts	amount of points in X and Y direction
_stepsize	distance between two points

void ge::CartesianGrid2D::create	(	const ge::AABB2d &	_bound,
		vmml::Vector2ui	_pointCounts
	)

Set up a cartesian grid based on a AABB with a specific amount of points.

Parameters

_bound	the bounds in x and y direction
_pointCounts	Amount of points in a certain direction. The stepsize is calculated based on the bound in x direction and the amount of point in x direction.

void ge::CartesianGrid2D::create	(	const ge::AABB2d &	_bound,
		double	_stepsize
	)

Set up a cartesian grid based on a AABB.

Parameters

_bound	the bounds in x and y direction
_stepsize	distance between two points. In case the bound coordinates are not a multiple of the stepsize the amount of points is a ceiled value to guarantee that all points are inside the bound.
